Evaluation of antibiotic prescribing patterns among inpatients using World Health Organization indicators: A cross-sectional study

Appropriateness of Antibiotic Prescription Among Children Under 5 Years: A Cross-Sectional Study in a Ghanaian Regional Hospital

Background and Aim

Misuse of medications, particularly antibiotics, severely impacts the standard of care and can result in antibiotic resistance. Antibiotic resistance is a growing problem in Ghana, compromising patient outcomes. This study aims to assess antibiotic prescription pattern and level of inappropriateness based on Standard Treatment Guideline (STG) recommendations in children under 5 years.

Methods

An analytical cross-sectional study design was used to assess antibiotic prescription in children under 5 years attending the Wa Regional Hospital in Ghana. Medical records of pediatric outpatients from January to December 2022 were reviewed. Patients' sociodemographic characteristics, prescribed antibiotics, principal diagnosis, dose, and duration were extracted using a semi-structured form. Prescriptions with clinical indication, dose, and duration which did not meet the requirements of the STG were coded as inappropriate. Data were analyzed and factors associated with inappropriate antibiotic prescription were determined using logistic regression.

Results

Children's mean age was 2.95 ± 1.20 years, with males comprising 54.5%. Most patients had NHIS coverage (90.6%). This study reports 62.7% (266/424) inappropriate antibiotic prescriptions in children under 5 years with infections. The most common classes of antibiotics wrongly prescribed were cephalosporin 54.3% (230/424), penicillin 21.7% (92/424), and aminoglycoside 12.5% (53/424). The class of principal diagnoses likely to have inappropriate antibiotic prescriptions included respiratory tract infections (aOR = 3.82; 95% CI = 2.13, 6.85; p < 0.0001) and urinary tract infections (aOR = 0.21; 95% CI = 0.11, 0.41; p < 0.0001).

Conclusion

Prevalence of inappropriate prescription of antibiotics was high among the study population, and this was strongly associated with respiratory and urinary tract infections. This study highlights the need to monitor antibiotic prescriptions in hospitals to ensure treatment effectiveness and combat antimicrobial resistance.

An evaluation of antibiotic prescription pattern and drug rationality analysis among outpatients at public health setting, India

BACKGROUND

Antibiotic resistance (AMR) is a significant worldwide health problem, with inappropriate antibiotic prescription being a major contributing factor. Prudent antibiotic use is essential for enhancing health outcomes and reducing AMR. This study assesses antibiotic prescribing practices and their logic in a public community health facility catering to 12,900 urban and rural populations in North India.

METHODS

Cross-sectional research was performed from August 2021 to August 2022, examining 1219 outpatient antibiotic prescriptions. The data encompassed medication kind, dose, duration, adherence to therapeutic criteria, and rationale evaluated by ID specialists and clinical pharmacologists. The evaluation was conducted in accordance with standard procedures, including those from NCDC and PGIMER. Demographics, antibiotic classifications, WHO AWaRe categories, diagnoses, and compliance with the essential drug list (EDL) were evaluated.

RESULTS

The results indicated that 45.9 % of prescriptions were for males and 54 % for females, predominantly involving individuals aged 20-40 years. Amoxicillin + clavulanic acid (27.2 %) was the most often given antibiotic, followed by metronidazole (13.4 %) and azithromycin (10.3 %). The WHO AWaRe categorization revealed that 49.7 % of antibiotics were categorized as "Access," 27.3 % as "Watch," and none as "Reserve." An examination of rationality indicated that 57 % of urinary tract infection prescriptions were justified, but just 29 % of respiratory tract infection prescriptions were deemed logical. Diarrhea and respiratory tract infections were recognized as primary targets for minimizing superfluous antibiotic consumption.

CONCLUSION

The research underscores the necessity for enhanced antibiotic prescription protocols in outpatient environments. Specialized education for healthcare professionals, improved prescription oversight, and compliance with evidence-based protocols are essential for fostering judicious antibiotic utilization and addressing AMR.

Point Prevalence Survey of Antibiotic Use in Level 1 hospitals in Zambia: Future Prospects for Antimicrobial Stewardship Programs

Introduction

The inappropriate prescribing and use of antibiotics have contributed to the emergence and spread of antimicrobial resistance (AMR). In Zambia, there is a paucity of information on the prescribing patterns and use of antibiotics among hospitalized patients in level 1 hospitals. This study investigated antibiotic use in five level 1 hospitals in Lusaka, Zambia.

Methods

This cross-sectional study utilized the World Health Organization (WHO) Point Prevalence Survey (PPS) methodology among in-patients admitted in level 1 hospitals before 08:00 a.m. on the survey day in August 2024. Data were analysed using IBM SPSS version 23.0.

Results

The prevalence of antibiotic use among inpatients was 59.0%, with ceftriaxone being the most prescribed. Antibiotics were prescribed mainly for paediatrics and male inpatients. This study found that 53.0% of prescribed antibiotics were from the Access group while 38.2% were from the Watch group of the World Health Organization Access, Watch, and Reserve (AWaRe) classification. Adherence to national treatment guidelines was 36.0%, with most antibiotics prescribed empirically without evidence of culture and sensitivity tests.

Conclusion

This study found a high use of antibiotics and low adherence to treatment guidelines in level 1 hospitals in Lusaka, Zambia. The findings of this study demonstrate the need to establish and strengthen antimicrobial stewardship programs and strengthen laboratory capacity to aid clinicians in diagnosing, treating, and managing patients across level 1 hospitals in Zambia.

Appropriateness of antibiotic prescribing among patients treated for dental diseases in Mekelle city, Northern Ethiopia: a cross sectional study

BACKGROUND

Local operative treatments are generally preferred for most dental diseases, with antibiotics only recommended as an adjunct in specific cases. Misuse and overuse of antibiotics has been shown to significantly contribute to the development of resistant bacteria. However, the antibiotic prescribing practices of dentists in Ethiopia have not been thoroughly studied. This study aimed to assess the appropriateness of antibiotic prescribing for patients with dental diseases at dental clinics in Mekelle City, Northern Ethiopia.

METHODS

A cross sectional study was conducted in April and May 2020 among patients visiting dental clinics in Mekelle City. Data were collected through patient medical record reviews and dentist interviews. The appropriateness of antibiotic prescription was evaluated based on guidelines from the American Dental Association and the European Society of Endodontology. Data were analyzed using SPSS Statistics, version 29. Binary logistic regression analysis was performed, and the results were presented as odds ratios with 95% confidence intervals. A p value less than 0.05 was considered statistically significant.

RESULTS

Two hundred and thirty-one patients with dental diseases participated in the study. The mean age was 30.6 years with a standard deviation of 16.1. Most participants had dental pulp related disease. 89% of patients were prescribed antibiotics, with amoxicillin being the most common. Inappropriate antibiotic prescribing was identified in 175 (75.8%) of the study participants. The most common inappropriate prescribing was unnecessary antibiotic prescribing for dental conditions without systemic signs, assessed in 141 (80.1%) participants. Patients diagnosed with pulp related disease without systemic signs and those who had tooth extractions were significantly associated with inappropriate antibiotic prescription (p value < 0.001).

CONCLUSIONS

The study findings show that antibiotics are over-prescribed for dental conditions in this resource constrained setting, especially in patients who have had tooth extractions. Dentists need training on appropriate antibiotic use and antimicrobial stewardship interventions should be implemented in dental setting to reduce unnecessary antibiotic prescriptions and prevent antibiotic resistance development.

Hospital prescribing patterns of antibiotics in Zambia using the WHO prescribing indicators post-COVID-19 pandemic: findings and implications

Background

Antimicrobial resistance (AMR) is a global public health problem that is fuelled by the inappropriate prescribing of antibiotics, especially those from the 'watch' and 'reserve' antibiotic lists. The irrational prescribing of antibiotics is particularly prevalent in developing countries, including Zambia. Consequently, there is a need to better understand prescribing patterns across sectors in Zambia as a basis for future interventions. This study evaluated the prescribing patterns of antibiotics using the WHO prescribing indicators alongside the 'access, watch and reserve' (AWaRe) classification system post-COVID pandemic at a faith-based hospital in Zambia.

Methods

A cross-sectional study was conducted from August 2023 to October 2023 involving the review of medical records at St. Francis' Mission Hospital in Zambia. A WHO-validated tool was used to evaluate antibiotic prescribing patterns alongside the AWaRe classification tool.

Results

Out of 800 medical records reviewed, 2003 medicines were prescribed. Each patient received an average of 2.5 medicines per prescription. Antibiotics were prescribed in 72.3% of encounters, of which 28.4% were injectable. The most frequently prescribed antibiotics were amoxicillin (23.4%-access), metronidazole (17.1%-access), ciprofloxacin (8%-watch) and ceftriaxone (7.4%-watch), with 77.1% overall from the 'access' list. Encouragingly, 96.5% of the medicines were prescribed by their generic names and 98% were from the Zambia Essential Medicines List.

Conclusions

There were high rates of antibiotic prescribing, including injectable antibiotics, which needs addressing going forward. It is crucial to implement targeted measures, including antimicrobial stewardship programmes, to improve future antibiotic prescribing in Zambia and reduce the risk of AMR.

Adherence to WHO guidelines on severe pneumonia management in children and its impact on outcome: an observational study at Jinka General Hospital in Ethiopia

Introduction

Poor adherence to guidelines during empirical antibiotic prescription in low-income countries could increase antimicrobial resistance without improving outcomes. Revised World Health Organization (WHO) guidelines published in 2014 on childhood (2-59 months) pneumonia re-defined the classification of severe pneumonia and changed the first-line treatment. The adherence to WHO guidelines in southern Ethiopia at the hospital level is unknown. We sought to determine the adherence to WHO guidelines on severe pneumonia first-line treatment in children in an Ethiopian referral hospital and assess the impact of non-adherence on patient outcomes.

Methods

An observational study was conducted on all children (2-59 months) clinically diagnosed with severe pneumonia and admitted to the Pediatric Ward of Jinka Hospital from 1 June 2021 to 31 May 2022. Exclusion criteria included a known HIV infection, ongoing antibiotic treatment before the event not related to acute pneumonia, or any other severe bacterial infection, confirmed or suspected. Adherence to guidelines was defined as first-line treatment with ampicillin or benzylpenicillin and gentamicin at the recommended dose. We compared the patients treated adherently vs. non-adherently. For categorical variables, the chi-square or Fisher's exact test was used, while for continuous variables, the Mann-Whitney U-test was used. Multivariate logistic regression was used to evaluate the association between adherence and demographic and clinical characteristics.

Results

During the observational period, 266 patients were registered as having severe pneumonia with an age between 2 and 59 months. After excluding 114 patients due to missing charts or other exclusion criteria, a total of 152 patients were included in the analysis. Of these, 78 (51%) were girls with a median age of 10 months (IQR 7-14). Overall, 75 (49%) patients received therapy according to the WHO guidelines. Compared to patients treated adherently to the guidelines, patients not treated adherently had similar outcomes [median length of stay of 3 (IQR 3-5) and 4 (IQR 3-6) days], median duration of oxygen therapy of 2 (IQR 1-3) for both the groups, and self-discharge rates of 5% and 6.5%, respectively).

Conclusion

Adherence to the revised WHO guideline was limited and not associated with outcomes. Efforts should focus on reducing the gap between theory and practice.

Diagnosis and Management of Adult Tuberculosis Patients Admitted to a Rural Hospital in Ethiopia

Background  Ethiopia is one of the countries in the world with the highest rate of tuberculosis (TB). The aim of this study is to describe the characteristics of the patients with TB admitted to a rural hospital in Ethiopia in terms of both diagnosis and clinical management. Methods A retrospective descriptive observational study was conducted. Data were collected from patients older than 13 years who were admitted to the Gambo General Hospital for TB between May 2016 and September 2017. The variables studied were age, sex, symptoms, human immunodeficiency virus (HIV) serology, nutritional status, presence of anemia, chest x-ray or other complementary tests, type of diagnosis (smear microscopy, Xpert MTB-RIF (Cepheid, Sunnyvale, California, USA), or clinical diagnosis), treatment received, outcome, and days of admission. Results One hundred eighty-six patients, aged 13 years and older, were admitted to the TB unit. About 51.6% were female, and the median age was 35 years (interquartile range (IQR) 25-50). Cough was the most frequent symptom on admission (88.7%), and contact with a TB patient was only recognized by 22 patients (11.8%). HIV serology was performed in 148 patients (79.6%); seven were positive (4.7%). About 69.3% met the criteria for malnutrition (body mass index (BMI) <18.5). Most patients, 173 (93%), presented with pulmonary TB and were new cases (94.1%). Patients were diagnosed by clinical parameters in 75% of cases. Smear microscopy was performed in 148 patients, of which 46 (31.1%) were positive, and Xpert MTB-RIF results were only obtained in 16 patients, of which 6 (37.5%) were positive. Chest x-rays were performed in most patients (71%) and were suggestive of TB in 111 (84.1%). The average length of hospital stay was 32 days (confidence interval (CI) 13-50.5). Women tend to be younger than men, have more extrapulmonary TB, and were admitted longer. Nineteen patients died during admission (10.2%). Patients who die were more frequently malnourished (92.9% of those who die were malnourished compared to 67.1% of those who did not die, p = 0.036), tend to be admitted for a shorter time than the survivors and receive more concomitant antibiotic treatment. Conclusions In this rural Ethiopian setting, patients admitted to the hospital for TB are often malnourished (67.1%), the main presentation is pulmonary, mortality is one in 10 admissions and very often receive antibiotics in association with TB treatment (40%).
